The unit shutdown method is directly related to the type of power machine used. If it is an internal combustion engine, the ignition switch or throttle can be turned off; if it is a motor, the switch can be pulled off to cut off the circuit. The Y/A starter motor can push the Y/A start switch to the park position. When the centrifugal pump is stopped, the pressure gauge should be closed first, and then the water outlet valve should be closed slowly, so that the power machine is in a light load state, then the vacuum gauge is turned off, and the power machine is finally stopped. If you drive again after parking for a long time, you should open the drain switch of each part and empty the inside of the pipe and the pump casing to prevent rust or cracks in the winter.
Maintenance and Troubleshooting of Centrifugal Pumps The working conditions of agricultural centrifugal pumps are generally rather harsh. In the working process, environmental conditions, mechanical vibration and other factors will affect the technical status of the centrifugal pump. The maintenance is to tighten and adjust the places where fastening and adjustment should be performed before the normal technical state of the unit has been damaged; replace the oil in time to maintain the normal lubrication conditions; observe various instrument monitoring devices frequently and find problems Troubleshoot the problem in time and let the crew always work in a good technical condition. Only in this way can the service life of the pump unit be extended to ensure that the unit will work with high quality and high efficiency.

Brief Analysis of Matters Needing Attention When Starting and Stopping a Horizontal Centrifugal Pump
Drive operation and shutdown When the horizontal centrifugal pump starts, after turning on the power machine to reach the rated speed, turn on the valves of the vacuum gauge and the pressure gauge and observe whether their pointer position is in the normal state. When it is normal, the outlet valve can be opened to the maximum value. When it is not necessary to monitor vacuum and pressure gauges, their valves can be turned off. When starting, attention should be paid to opening the outlet valve as short as possible. The operating time of the pump in the closing state of the gate valve should not exceed 5 meters, so as to avoid causing the temperature of the water in the pump to be too high and causing heat to distort or damage the components. During the operation of the water pump, the operator must strictly observe the post, strengthen the inspection, find the problem in time, and ensure the safety of the operation.
